This research is a quantitative research with analytical observational design and cross sectional approach. The population is heavy equipment operators with a total of 32 people and the sampling technique used is exhaustive sampling. The data collection instruments were whole body vibration, reaction timer, rapid entire body assessment (REBA), oswestry disability index (ODI) questionnaire, interviews and observations. Data analysis in this study is using path analysis. The results of the path analysis showed that there was a direct effect of age (p=0,000) and work position (p=0,009) on low back pain and there was an indirect effect of whole body vibration on low back pain (p=0,029). Meanwhile, working period showed no direct and indirect effect on low back pain. Therefore, the company should adjust the work based on the age and physical ability of heavy equipment operators and improve the quality of ergonomics training.
